Image pickup apparatus having wiring board with alternately arranged flying leads

Abstract

An image pickup apparatus includes: an image pickup device including a light receiving surface, an opposite surface, and an inclined surface inclined at a first angle, and provided with light receiving surface electrodes on the light receiving surface; a cover glass; and a wiring board including a first main surface and a second main surface, and including wires each connected with each of the light receiving surface electrodes, back surfaces of the light receiving surface electrodes are exposed to a side of the opposite surface, distal end portions of the wires are flying leads bent at a second angle in a relation of a supplementary angle to the first angle and connected with the light receiving surface electrodes, and the second main surface at a distal end portion of the wiring board is directly fixed to the opposite surface arranged in parallel with the second main surface.

What is claimed is: 
     
       1. An image pickup apparatus comprising:
 an image pickup device comprising:
 a light receiving surface where a light receiving portion is formed, 
 an opposite surface opposing the light receiving surface, and 
 an inclined surface inclined at an acute first angle to the light receiving surface, the light receiving surface being provided with a plurality of light receiving surface electrodes electrically connected with the light receiving portion the plurality of light receiving surface electrodes being formed on the light receiving surface; 
 
 a transparent cover glass joined so as to cover the light receiving surface; and 
 a wiring board comprising:
 a first main surface, 
 a second main surface, and 
 a plurality of wires each connected with each of the plurality of light receiving surface electrodes of the image pickup device, 
 
 wherein the transparent cover glass and the plurality of light receiving surface electrodes are extended to an outer side of an end side of the inclined surface, the light receiving surface electrodes extending from the light receiving surface to an extended surface of the transparent cover glass, 
 back surfaces of the light receiving surface electrodes are exposed to a side of the opposite surface, 
 respective distal end portions of the plurality of wires are flying leads bent at a second angle in a relation of a supplementary angle to the first angle and electrically connected with each of the light receiving surface electrodes, 
 the second main surface at a distal end portion of the wiring board is directly fixed to the opposite surface of the image pickup device arranged in parallel with the second main surface; 
 the image pickup device includes a plurality of inclined surface electrodes respectively extended from the plurality of light receiving surface electrodes to the inclined surface, 
 the plurality of flying leads are formed of alternately arranged first flying leads and second flying leads, 
 the first flying leads are bonded with the inclined surface electrodes on the inclined surface, and 
 the second flying leads are bonded with the light receiving surface electrodes on the extended surface of the transparent cover glass. 
 
     
     
       2. The image pickup apparatus according to  claim 1 ,
 wherein a plurality of first bond electrodes are disposed on the opposite surface of the image pickup device, 
 a plurality of second bond electrodes are disposed on a distal end portion of the first main surface of the wiring board, and 
 each of the plurality of first bond electrodes is solder-bonded with each of the plurality of second bond electrodes. 
 
     
     
       3. The image pickup apparatus according to  claim 1 , wherein the second main surface at the distal end portion of the wiring board is directly fixed to the opposite surface of the image pickup device to the distal end of the second main surface.
